Abstract
The reported preparation of 1,2,3,4-tetrafluoro-3,4-dichlorocyclobutene from commercial 1,2,-dichloro-1,2-difluoroethylene when carried out in stainless steel reaction vessels also yields some 3,3,4,4-tetrafluoro-1,2-dichlorocyclobutene. Reactions of the 3,3,4,4-tetrafluoro-1,2,-dichlorocyclobutene with the sodium salts of the metal carbonyl anions [C 5H 5Fe(CO) 2] - and Mn(CO) 5 - results in replacement of a vinylic chlorine atom with a metal atom to give yellow-orange C 4F 4ClFe(CO) 2 -C 5H 5 and white C 4F 4ClMn(CO) 5, respectively. Reaction of C 4F 4ClFe(CO) 2C 5H 5 with triphenylphosphine, preferably in the presence of ultraviolet irradiation, gives the triphenylphosphine derivative C 4F 4(ClFe(CO)[P(C 6H 5) 3](C 5H 5). The mass spectra of the new metal fluorocarbon complexes are discussed.
